A heat exchanger with a disc ring guide plate and a cone end plate discloses a heating gas boiler. The upper and lower ends of a group of smoke pipes 2 are respectively put through a group of holes of the upper cone end plate 1 and the lower cone end plate 7 for close welding; the middle part is put through the upper ring guide plate 3, the disc guide plate 4 and the lower ring end plate 5 from top to bottom. The upper cone end plate 1 is the bottom of the boiler combustion chamber 9. The gas passes through a group of smoke pipes 2, heating the pipe wall, and then heating the water in the pipe box 6. After heat release, the gas is cooled and discharged into the condensate water tank 8 connected under the heat exchanger. The tube box 6 is surrounded by an integrated combustion chamber 9 and a heat exchanger, under which there is a water inlet to introduce cold water, and on which there is a water outlet to discharge hot water. The heat absorption surface of the upper cone end plate 1 is larger than that of the flat end plate, which improves the heat absorption rate of the heat exchanger; the lower cone end plate 7 is favorable for the condensation water to slide down and avoid the corrosion of the plate surface; the inter phase disc ring guide plate makes the water flow in the heat exchanger fully absorb heat, which improves the heat efficiency of the boiler. Used for heating gas boiler.

有盘环导板和锥端板的热交换器
有盘环导板和锥端板的热交换器涉及采暖锅炉技术,具体涉及一种采暖锅炉的热交换器。
技术介绍
民用燃气锅炉用热交换器吸收燃气在燃烧室产生的热量,把水加热来供暖或供生产生活热水。现行燃气锅炉的热交换器为管箱式换热器,多在圆筒形箱体的上下端板之间并连一群烟管,使燃料产生的高温气体经烟管通过,加热烟管外流动着的水。为了增加水的吸热效率,须增加吸热水的扰动,变层流为紊流,现行换热器中加有几层圆缺式,即整圆切去一块弓形的导流板。现行管箱式的上下端板,虽用不锈钢板制造,但是由于不锈钢材质不均匀性,有非不锈斑纹,遇酸性介质仍会锈蚀。现行管箱式换热器的上下端板为平板,容易驻留冷凝水,天久日长,仍有材质瑕疵点锈损。
技术实现思路
有盘环导板和锥端板的热交换器要解决的技术问题是:增加热交换器的吸热率和防腐性。采用的技术方案是:管箱的上下端板采用圆锥形,箱内的导流板采用相间的圆环导板和圆盘导板。有盘环导板和锥端板的热交换器(图1)由上锥端板1、一组烟管2、上圆环导板3、圆盘导板 ...
